The end 126 of the lever 117 is bifurcated and straddles an enlarged intermediate portion 128 of a stud 127, whichextends throu h a slot 129 in the housing 2.

yThe protrucmg end 130 of the stu-d 127 is threaded to receive a knob 131, which is used` yfor clamping purposes, as will presently be described. Ther portion of the 'stud 127 which rests in the slot 129 inthe housing 2 is provided with flat faces 132 with the sides of the slot 129,a'nd'perm1t the vstud 127 to be raised or lowered in the said slot 129, butprevents the same from turning therein, A bushing 133 provided with flat faces 134 rests in the slot 116 in the depend- -ing leg 115 ofthe rocker arm 38, and is adapted to slide in the said slot 116 for purposes as 'will presently be described.A vThe end 135of the stud 127 extends through a central orifice in the bushing 133 in the slot 116, and its protruding end 135 is threaded to receive a nut 136, a suitable washer 137 being placed between the nut 136 and the face of the depending legl 115 of the rocker arm 38. rThe portion of the stud 127that extends through the bushing133 is slightlyy longerthan the bushing -133,-so that when the nut 136 is turned down, the washer 137 will be locked but at the same time allow the which register o bushing 133 to rock on the stud 127 and permit the. bushing 'to slide in the slot 116,. yThe knob 131 which is threaded u on they end 130 of the stud 127 which protrudes through the slot 129 in the housing 2, when turned down locks thestud 127 `in its adjusted position, which adjustment is obtained lthrough the agency of the lever 117 and knob 125, secured to theA rod 123, which is .providedvwith the pinion 122,y which meshes with the toothed rack on the lever 117.

A square block 140 provided 4with integrally formed studs 141 and 142 are adapted to yreceive bushings 143 and 144 which rest in the slots 145 and146 inthe upper ends of the plates 40 and 41 which form the rocker arm 38. lThe block 140 rests between the upper ends of the plates 40 and 41 of the rocker `arm 38, when in position with its supported bushings 143 and 144, resting in the slots 145 and 146, and the end of the stud 141 which protrudes through the bushing 144 supports a shoe 147 which rests in a slot or channel 148 cut inthe inner face of the housing 2. Thek end of the stud 142 which protrudes through the bushing 143 has secured thereto, bymeans o f'a set screw, a shoe 149 which rests in a slotor channel 150 cut in the innerv face of the cover cap 55, when the same is in position, and secured to the housing 2. The block 140 is provided with a central orifice 151, which is adapted to receive a guide rod 152 which4 is adapted to be secured therein by means of a drive fit. This guide rod 152 extends through a-guide bearing 153, and serves as a guiding means for the rocker arm 38 in its to and fro travel, as will presently be described. Thevshoe 149 secured to the. stud 142 is provided with an orifice 154 which is adapted `to receive the end of the distributing bar 112, and secured therein by means of a. drive lit. This distributing bar 112 extends through an aligned orifice 155 in the side 5 of the housing 2 to which the distributing arm D is secured.

The sliding member 37 to which the rocker arm 38 is pivotallysecured, and which member 37 and arm 38. asa whole, are slidably supported on the shaftV 33, has secured to it by suitable means, a cam follower member 156 which is provided with a knife edge nose 157, which is held in engagement with either of the faces 29 and 30 of the cam member 28, depending upon the position of the cam member 28, by meansof a helical spring 158 around the shaft 33, and `which spring 158r rests between the bearing 34 which vvsupports the shaft 33 and the sliding member 37 on the shaft 33. 4

Referring now to Figs.1 1 to 3, I show a distributor arm D` secured to the reciproeating shaft or distributing bar 112. l

The distributor D comprises a plate 160 provided with an orifice 161 which adapted to receive a bushing 162 which is held therein by means of a force fit, and the plate 160 and its bushing 162 are in turn slidably supported on the distributing bar 112.. A' split clamping member 163 is provided withan orifice 164 which permits .thelsame to be slipped onto the dis-y tributing bar 112, anda clamping .screw 165 when tightened, `clamps the `member 163on .the distributing bar 112. The plate 160 has secured toit a sleeve member 166 provided withan internally threaded portion 167,v and an enlarged ortion which enlarged'vportion is adapte ,to` receivea sleeve member 168 secured to the clamping member 163. VA pin 169 provided with a threaded end portion 170 extends through the sleeve member 168 on the clamping member 163, its threaded end vportion 170 havino screw-threaded engagement' with the threat edportion 167 of the sleeve 166 vsecured to the member 160. VThe pin 169 is provided with a -knob 171 which facilitates the turningot` the lpin 169, and when'ithe plate 160 slidably supportedwon the distributing bar 112 and the Vclamping member;

163 are operatively linked together by means of the rotatable ypin 169, the knob 171 secured thereto `rests againsty the v clampiner member 163 and ,the sleeve 168 secured.

thereto extends .into the sleeve member 166 secured to the plate 160. With the parts just described linked together by means of the rotatable pin 169, it may readily be seen that when the pin 169 is lturned to the right or left with reference to Fig. 2, the plate 160, which ispslidably supported on the-dis-k tributing bar 112, is moved to the right or left, as the case may be. This is accomplished by reason that the clamping member 163 is secured to thevdistributing bar 112, and as the plate 160fis slidably supported onthe distributing bar 112, the turning of the knob 171 secured to the pin 1691causesthe threaded end 170 of the pin l169, which v is in threaded engagement with the threaded portion 167 of the sleeve 166 lsecured to the late 160, to move the same to the ri hty or eft, for purposes as will presently described. The sleeve 168 on the clam ing member 163 which extends into the s eeve 166 on the pla-te 160 serves` as guiding means for the plate 160 as it is moved to theright oryleft, and also maintains they plate 160 slidably vmounted on the distributing bar 12 in its vertical position. An arm 172 pivotally secured to the plate supports v a pair of ball bearing guide wheels 173 the wire from the source of supply to the coil secured in the chuck C.

The plate 160 is provided with al pinsecured to its upper` and 174 yfor the usual purpose of guiding.

the stud 176 and is threaded and adapted to receive a thumb nut 17 7 A helical spring 178 of a size to be slipped over the vstud 176 on vthe arm 160 rests between 'the face of the arm 160 and the thumb nut 177, so that las the thumb nut 177 is turned down, the

172 and the face of the plate 160. The

means for adjusting the plate 160 and its pivoted adjustable arm 172, as a whole, to the right or'left, will be more fully hereinafter described. f

The chuck C for gripping the electromagnet spools 190 is provided withy a body portion 22 which, asy already described, is secured to the spindle shaft 3 and is provided with slots 180 in which the jaws 181 are pinned by the pivot pins 182. An internallyl threaded? ring member- 183 has screwthreaded engagement with the threaded portion 184 of the body'22 of the chuck,

and is provided with an annular internal lip 185. The jaws 181 areprovided with tapered faces 186, and through the agency of helical springs 187 which rest between the jaws 181 and the bottom of the slots 18,0, the free`ends of the jaws 181 are forced outward.' The body portion 22 is also provided with a threaded stud 188 integrally formed therewith and the core of the spool 190 in its one end is provided with a suitable tapped orifice which is adapted to be threaded on the threaded stud 188 to rotatably secure it to the spindle shaft 3, as shown dottedin Fig. 4. To secure the spool 190 against rotation-relative to the spindle shaft 3, afterbeing threaded upon the stud 188, the ring member 183 is turned to be moved forward causing its li 185 to engage the tapered faces 186 of t e'jaws 181, forcing them inward against the tension of the helical springs 187, causing the jaws 181 of the chuck C to engage the head 191 of the spool 190 and grip the same to clamp the spool 190 in the chuck C against movement of the spindle shaft 3.

The removable cover cap is secured to the housing 2 by suitable screws which have screw-threaded engagement with suitable tapped orifices in the housing 2. This cover cap 55 may be removed to permit access to the mechanism of the machine. The housing 2 is also provided with a suitable base 193 and the machine may be secured to a suitable table and a strand of wire 194 from a suitable source of supply lead over the guide wheels 173 and 174 on the adjustable arm 172' of the distributor D to the spool 190 to be wound.,

Having described the apparatus through `the agency of which the cam member 28 is rotated, and the apparatus associated therewith for controllingA the length of stroke of the distributing bar112z I will now describe the operation of the `wlnding machine and the adjusting means for adjusting the length of the stroke of the distributing bau 112 from left to right, and vicey versa. Now, when 'the clutch pedal of the power drive (not shown) is actuated, the'belt connection between the source of power and the pulley 4 on the spindle shaft 3 will rotate the spindie shaft 3. The worm 76 on the shaft 3 meshes with the worm gear 59, causing rotation of the worm gear 59, and throu'gh the agency of the piniony 5801i the'transverse shaft 57 upon which the worm gear 59 is secured, and the gear wheel 60 rotatably supported on the arm 61 and the gear wheell 56 and bevel pinion 52 on the transverse shaft 53, and the bevel gear wheel 51 on the shaft 33 rotary motion is transmitted to the shaft 33 which carries the cam member to cause j rotation of the cam member 28'. In the drawings lI show the distributing bar 112 in an intermediate position, that is, half way between its left and right adjusted position, and with reference to Fig. 4, theV arrow indicated on the cam member 28 indicates. the direction of travel of the cam member 28 and with this directionof travel,

the distributing bar 112 is traveling to thel right with reference to Fig. 4. j

As the cam member 28 rotates, the nose 157 of the cam follower 'member 156 follows the contour of thereceding pitch face 29 of the cam member 28, and through the agency of the helical spring 158 which bears against the sliding member 37, the said member 37 and its pivotally sup orted rocker arm 38 as a whole, continue t eir travel to the right with reference to4 Fig. 4, but as the stud 127 which is used for adjusting the length of stroke of the distributin bar 112 asses through the slot 116, in the epending eg 115 of the rocker arm 38, as before described, is locked in its adjusted position in the slot 129 in the housing 2 by means4 of the locking knob 131, the rocker arrn 38 rocks about this point and pivots about its pivot pins 39 in the sliding member 37 and causes the upper end of the rocker arm 38 to tilt to the right. The shoes .147 and 149 supported on the block resting in the upper end of the rocker larm 38 now slides to the right in their respective channels 148 and 150.

The tilting of the upper `endo-f the rocker, arm 38 to the right in a downward direction is permitted, due to the fact that the studs 142 and 143 of the block 140 which support the same in the rocker arm 38 rest in the bifurcatedtends of the rocker arm 38, and at the same time 'permit the shoes 147 and 149 of the` block 140 to move in a horizontal plane to the right. l The bushing 144 in the-slot 116 inthe leg 115ofthe rocker' arm' 38 is slidably secured-therein, as previ ouslydesoribed, and as the lowerfend of the leg 115 ofthe rocker arm'38moves tothe left the bushing'aroundthe locked stud 127 rotates thereon to permit this movement to lthe left in4 an upwarddirectionof thelleny 115 of the rockerarm 38. Theqguide rod 152 secured-l tothe shoe slides through the" guide bearin A153 and the combination of member y28 in which .position the -distribut'` ling bar 112 is. in its extreme rightipositionwith reference to Fig. 4. The nose 157 ofy the cam follower 156 now engages the pitch face' 30'of the camy member 28,causing the` nose 15,7 to follow the contourof'the cam face 30,; thusforcingI the sliding member 37 and. its supported pivote'd rocker arm'38to the left., causing the upper end/to swing to the left to cause the shoes 147 and 149 to move to the left in their respective channels 148 and j 150, This movementof therocker :112111138 and its associated parts continues to theleft until thenose 157 of the cam'follower 156 reaches the apex 201 of the cam4 28 and the instant that the nose 157 of the cam-follower 156 passes the apex 201, thecam face 29 of the cam member 28 isagain engaged and the slid` ing members37 and its pivoted rocker arm 38 and its associated parts again-move to the right with reference to Fig. V4, under tension ofthe compressed`spring158.` i'

yFrom thev above `description it may be seen that the tilting of theupper end of the Vrocker arm 38y fromfleft `to rlghtyand vice versa, causes the shoes 147 .and 149 to travel l in a like direction, and as the 'distributing bar 112 is secured to the shoe 149,'the said distributing bar 112 also receives this to' and fro movement. It will also bey seen that the rotationof the cam member v28,through the agency' of the cam ,follower v156,' sliding member 37, the rocker arm 38 and theshoes 147 and '149 brings about the movement ofthe reciprocatingl shaft'o'r distributing bar 112 from left to right,A and vice versa, and that-for one complete revoluton of the `cam me'nber 28, the'l distributing` .bar 112 will have traveled from left to right and from right to left, and as' the distributing-arm 172 is securedto the bar 112.*two-,1ayers of couvolutions `of wire have beenzplaced on the spool 1,90 grippedv bythe chuckY Csecured to thesoindle shaft 3.

The length ofthe stroke kof the diisltribut- :ing bar 112 is adjustable, and'to this end I f 4the bushing 133 supported thereonrocks, decreases the dista-nce that thel upper 0nd `of f the-'rocker arm 38 tiltsfrom' leftv to right.

yitsA other 'end being bifurcated, straddles the enlarged intermediate portion 128 of the stud 127 which extends through the'slot 1291 in the -housing'2 and the slot 116 inthe lleg 115 vofthe rockerarm"38,as already desy scribed. New." to. adjust the stroke of' the` distributing barf112 the rocking knobA 131 which isin the threaded,'engagement'.with the threaded end 130 of the stud 127,@ is loosened or unscrewedto permit the stud to be moved in the slot 129 inthe housing 2 and theslot 116 in the legfof the "rocker arm 38.`- As shown'in Fig. '8,th'e stud 127 -is in itsextreme upper position in* which position the distributingbai-"112 moves frolnleft tojright and vvice f versa, its maximum distance' or l stroke', which "inthe instant vcase-is about' two and' one-eighth inchesfNow to decrease the stroke. the locking yknob 131' is' loosened as just-:described to y"permit the adjusting knob 125 to beturncd. This knob 125 when v turned in the direction of the arrow, asl indicated in Fig. z4', causes the pinion 122asso-` ci'ated 'withthe knob 125, and which is in y meshfwith` the toothed rack on the adjusting j lever 11740 rock the lever about its pivot '118 and move the b'ilfurc'aited end whichsti'addles the stud 127 downward. This movement of the end of thelever'117 also moves tl1c'"stud miy -127 down andv asfthe bushing 133 is supported bushing `133 in the's'lot 116i'ncreases the distance between thehorizontalfslidablc y pivotedfccnter of the rocker arm 38 and the fixed locking center. which in lthis case is the stud 127. This increase of distance be`- tween-the pivoted. centers 39 of the rocker arml 38 intermediate of itsends, andthe fixed locking center or stud 127 'about which and? vice versa,and as they distributing bar 112 is secured to the shoe'149,' whichzis asso 'ciated with thisltiltingend of therocker 115 arm 38, the distance that/the' distributing bar 112 travelsffrom left'to right andY from right to left-isdecreased..

From the above descrlption, it is readily ratelyradjus'ting'the.-length of its strokel and it isalso apparent from the description that the adjusting means is lnicrometrilc in that it provides an infinite numberjof ad- 125 justable positions forthe fixed locking center'or stud 127 to provide an' infinite n'um-' ber offlength'"ofjtrarel of the:distributing` bar'112. W'hen an adjustment of thel distributing bar j is obtained for a certain 1,30'l

vus

length of coil to be wound, the locking knob 131 is again tightened to clamp the stud'127 in its adjusted position in the slot 129 in the' housing 2, to maintainv ythe adjustment.

y From thisv it is apparent that the machine ot' my invention is adaptable. for various lengths of coils, and that it is a simple Inat-v `ter to change the stroke or distance of travel 0f the distributing bar-=112 by this simple adjusting means without the .necessity of changing gears; or substituting' cams pro` videdwith different pitch cam faces.

Spools, such as are illustrated in dotted line in Fig.- 4 uponwhich the Vconvolutions of wire are wound, are provided with spool kheads between whichthese convolutions of 'ohmieresistance Now, it often happens,

due to the inaccuracies in manufacture, the distance between the spool heads varies slightly, and as a predetermined number of convolutions of wire must be placed thereon, if no provisions were made for adjusting the distributing bar 112 -to overcome this, it maybe readilykseen that if the distance between the spool heads wasa trifle over its fixed predetermined dimensions, that there would be a slight space vbetween the inner faces of the spool heads and the layers of wireon the spool, permitting. these unsupported ends to loosen, whereas, if this distance is below its fixed predetermined dimension, the first few end turns of each endv of the layers would. pile up. and form a bulge at each end of the coil, which would be magnified as each successive layer is placed thereon. With the adjustable means `for giving the distributing bar k112 an infinite number of lengths of travel from leftto right, and right to leftit isreadily apparentv that after the first layer of convolutions ofwire are placed on thespool, the

operator can readily observe either of these v discrepancies, and kin either case, the operator may adjust the distributing bar 112 to increase or decrease the distance of' travel from left to right, and vice versa, to overcome this variance of distances between the spool'heads by the simple adjusting means which includesv the knob 125 and its asso-l ciated lever 117.

It sometimes happens that the distance between the spool heads is constant, but, due to the manufacturing inaccuracies, the heads are placed at varyingV distances along the core of the spool, so that when they'are clamped in the chuck C, the first layer when wound on the core will-reveal this discrepancy, and I provide the adjustable means associated with the distributing arm 172 so lPatent is that the operator by turning the knob 117 of the threaded pin 169 will move the plate 160 slidably supported on the distributing bar 112, and its pivotallysupported distrib` uto'r arm 172, as awhole, to the rightor left, as the case may be, tofcenter the spool with relation to the distributor arm 172, so that the convolutions will be placed thereon the full distance between .the spool heads with? out a pilingup at one end of the core and a space between ythe end of the layer andthe face of' the spool head, as would be the case if this adjustment were not provided.

From the foregoing it is readily: a pary ent that the rotation of the'drive shaft not 80l only causes the winding of` convolutions of" wire-upon the magnet spool, but also causes thek movement of the distributor member back and forth, and that the mechanism for accomplishing thisresult is very compact and enclosedin a casing away from dust and injury.` f

lf it is desired to place a different number of convolutons of wire on the spool, all that is necessary to do is to change the gearing V ratiobetween the drive shaft and the distri buting member. It will be noted that the arm (S1 is provided with a y slot so that different size gears may be secured'tothis arm in mesh with gears -59 and 5G. 95

The rotation of the drive shaft also transmits motion to the gears yassociated with the counter mechanism thereby causing the hands ofthe counter to visualize the num- Y, ber ofl revolutions of the driving shaft. The counter mechanism is all enclosed ina housing-or casing, and is so situated that the visualizing mechanism of the counter devicel is immediately before the operator ofthe winding' machine.

As before mentioned, the operator can change the distance of travel of' the feeding vmechanism while the iwinding machine is` in operation, and the .operator can also adjust the distributing'mehanism to feed fur- 110 ther to the right'or left while the machine is lin operation. V
